Istanbul's Digital Image Replacement Efforts: A Global Comparison

Istanbul's municipal government has launched a new initiative to replace duplicate images in the city's digital archives, with a focus on preserving historical and cultural heritage. The project, which began in January 2026, aims to reduce storage costs and improve data management efficiency.

The effort is particularly significant in the wake of the 2023 Kahramanmaras earthquake, which highlighted the importance of preserving cultural and historical records. With the Turkish lira experiencing high inflation rates, the cost of storing and maintaining duplicate images has become a significant burden for the city's budget. Furthermore, the integration of the Syrian refugee community has also brought attention to the need for efficient data management, as many refugees have brought their own digital archives with them.

In Istanbul, the project is being led by the Istanbul Metropolitan Municipality's (IBB) Department of Culture and Tourism, in collaboration with the Turkish Ministry of Culture and Tourism. Specific locations such as the Hagia Sophia Museum and the Topkapi Palace are being prioritized, with teams working to replace duplicate images in their digital collections. The IBB is also working with local organizations, including the Istanbul University's Center for Byzantine Studies and the Turkish Historical Society, to ensure the accuracy and authenticity of the replaced images.

Comparing Istanbul's Approach to Other Global Cities

Compared to other major cities, Istanbul's approach to duplicate image replacement is unique. Tokyo, for example, has implemented a city-wide data management system that uses artificial intelligence to identify and replace duplicate images. In New York City, the Department of Cultural Affairs has established a digital archives program that prioritizes the preservation of historical and cultural records. According to data from the IBB, the city's digital archives contain over 1.5 million images, with an estimated 20% being duplicates. The cost of storing these images is approximately 1.2 million Turkish lira per year, which is equivalent to around $65,000 USD.

As the project moves forward, the IBB plans to implement a new data management system that will use machine learning algorithms to identify and replace duplicate images. The system, which is expected to be launched in 2027, will be developed in partnership with the Turkish technology company, Turkcell. In the meantime, residents and visitors can expect to see improvements in the city's digital archives, with more accurate and efficient access to historical and cultural records. For those interested in learning more about the project, the IBB will be hosting a series of workshops and seminars at the Istanbul Congress Center, starting in September 2026.
